  • Data Science is Hard: Validating Data for Glean

    Glean is a new library for collecting data in Mozilla products. It’s been shipping in Firefox Preview for a little while and I’d like to take a minute to talk about how I validated that it sends what we think it’s sending.

    Validating new data collections in an existing system like Firefox Desktop Telemetry is a game of comparing against things we already know. We know that some percentage of data we receive is just garbage: bad dates, malformed records, attempts at buffer overflows and SQL injection. If the amount of garbage in the new collection is within the same overall amount of garbage we see normally, we count it as “good enough” and move on.

    [...]

    At this point, aside from the “metrics” ping which is awaiting validation after some fixes reach saturation in the population, Glean has passed all of these criteria acceptably. It still has a bit of a duplicate ping problem, but its clock skew and latency are much lower than Firefox Desktop’s. There are some outrageous clients sending dozens of pings over a period that they should be sending a handful, but that might just be a test client whose values will disappear into the noise when the user population grows.

  • It’s time for the US Senate to Save the Net

    On the one year anniversary of the Federal Communications Commission’s repeal of net neutrality, Mozilla is joining millions of people across the internet to once again stand up to protect the open internet.

    When the FCC gutted net neutrality protections last year, we filed our lawsuit because we believed that repeal was unlawful. We also believed taking on the FCC was the right thing to do for the future of the internet and everyone who uses it.

    Until the Senate listens to the American people and protects the open Internet, Mozilla v. FCC continues to be net neutrality’s best hope.

    But it’s time our Senators do what they were elected to do – represent their constituents, and pass net neutrality legislation that has overwhelming support and protects Americans. With a victory in the courts, or bipartisan legislation, we can ensure that people – and not big cable and telephone companies – get to choose what they see and do online.

Debian May Need To Re-Evaluate Its Interest In "Init System Diversity"

Debian Project Leader Sam Hartman has shared his August 2019 notes where he outlines the frustrations and issues that have come up as a result of init system diversity with some developers still aiming to viably support systemd alternatives within Debian. Stemming from elogind being blocked from transitioning to testing and the lack of clarity into that, Hartman was pulled in to try to help mediate the matter and get to the bottom of the situation with a lack of cooperation between the elogind and systemd maintainers for Debian as well as the release team. Elogind is used by some distributions as an implementation of systemd's logind, well, outside of systemd as a standalone daemon. Elogind is one of the pieces to the puzzle for trying to maintain a modern, systemd-free Linux distribution. Read more
